Compressive Strength Test Of Concrete - Detailed Guide

As per IS 456, the individual compressive value of a concrete cube should not be less than 75% of its grade. Example – If the concrete grade is M20, then the individual crushing value should not be less than 15 N/Sqmm. The individual crushing value difference between the cube should not be greater than 15%. Hope you enjoyed the topic.
